Wetland is one of the three major ecosystems on the earth and has fundamental ecological functions and plays an irreplaceable role in serving biological survival and human development. Considering the characteristics of five types of wetlands, this study constructed a wetland ecological health evaluation indicator system using a wide variety of data from statistical report, field sampling, remote sensing, and questionnaire survey. In this study, we have selected 13 indicators (related to water, soil, biological, landscape and social factors) for ecological health evaluation of 19 wetlands in Beijing-Tianjin-Hebei region of China which have national importance. The detailed analysis shows a comprehensive health index of 5.53. There was significant spatial heterogeneity in the health status of the 19 wetlands in this region. The evaluation results and analysis provides scientific services for developing reasonable and targeted wetland protection and utilization policies of wetlands.
湿地是地球上三大生态系统之一,具有基本的生态功能,在服务生物生存和人类发展方面发挥着不可替代的作用。考虑到五种湿地类型的特点,本研究利用统计报告、野外采样、遥感和问卷调查等各种数据,构建了湿地生态健康评价指标体系。在本研究中,我们选择了 13 个指标(与水、土、生物、景观和社会因素有关),对中国京津冀地区具有国家重要性的 19 个湿地进行了生态健康评价。详细分析显示,综合健康指数为 5.53。该地区 19 个湿地的健康状况存在显著的空间异质性。评估结果和分析为制定合理的、有针对性的湿地保护和利用政策提供了科学服务。
